Network Infrastructure

Network infrastructure is the set of components and concepts that help traffic reach the right application reliably and efficiently.

It includes:

• Distributing traffic across servers.
• Proxying requests to backend services.
• Serving content from edge locations.
• Identifying services using ports.
• Writing programs that communicate over sockets.
